详细描述

The Shortcut type lets you handle keyboard shortcuts. The shortcut can be set to one of the 标准键盘快捷键 , or it can be described with a string containing a sequence of up to four key presses that are needed to activate the shortcut.

Item {
    id: view
    property int currentIndex
    Shortcut {
        sequences: [StandardKey.NextChild]
        onActivated: view.currentIndex++
    }
}
					

It is also possible to set multiple shortcut sequences , so that the shortcut can be activated via several different sequences of key presses.

This property holds whether the shortcut is enabled.

默认值为 true .

This property provides the shortcut's key sequence as a platform specific string. This means that it will be shown translated, and on macOS it will resemble a key sequence from the menu bar. It is best to display this text to the user (for example, on a tooltip).

另请参阅 sequence and portableText .

This property provides the shortcut's key sequence as a string in a "portable" format, suitable for reading and writing to a file. In many cases, it will look similar to the native text on Windows and X11.

另请参阅 sequence and nativeText .

This property holds the shortcut's key sequence. The key sequence can be set to one of the 标准键盘快捷键 , or it can be described with a string containing a sequence of up to four key presses that are needed to activate the shortcut.

The default value is an empty key sequence.

Shortcut {
    sequence: "Ctrl+E,Ctrl+W"
    onActivated: edit.wrapMode = TextEdit.Wrap
}
					

注意： Given that standard keys can resolve to one shortcut on some platforms, but multiple shortcuts on other platforms, we recommend always using sequences for standard keys.

另请参阅 sequences .

This property holds multiple key sequences for the shortcut. The key sequences can be set to one of the 标准键盘快捷键 , or they can be described with strings containing sequences of up to four key presses that are needed to activate the shortcut.

Shortcut {
    sequences: [StandardKey.Cut, "Ctrl+X", "Shift+Del"]
    onActivated: edit.cut()
}
